Information
Grub screws GN 632.1 with ball point are as a rule used with thrust pads GN 631 / GN 631.5 .
The ball-Ø d2 is smaller than the thread core-Ø, which allows fitting over the ball end.
The combination of grub screws GN 632.1 and thrust pads GN 631 GN 631.5 with gripping elements easily makes clamping screws of many different types.
